Introduction

A plasma globe using electrical energy to create plasma, light, heat, movement, and a faint sound

Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the capacity to do work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J).

Forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, the internal energy contained within a thermodynamic system, and rest energy associated with an object's rest mass. These are not mutually exclusive.

All living organisms constantly take in and release energy. The Earth's climate and ecosystems processes are driven primarily by radiant energy from the Sun. (Full article...)

The Organization of the Petroleum Exporting Countries (OPEC /ˈpɛk/ OH-pek) is an organization enabling the co-operation of leading oil-producing and oil-dependent countries in order to collectively influence the global oil market and maximize profit. It was founded on 14 September 1960 in Baghdad by the first five members: Iran, Iraq, Kuwait, Saudi Arabia and Venezuela. The organization, which currently comprises 12 member countries, accounted for 38 percent of global oil production in 2022. It is estimated that 79.5 percent of the world's proven oil reserves are located within OPEC nations, with the Middle East alone accounting for 67.2 percent of OPEC's total reserves.

In a series of steps in the 1960s and 1970s, OPEC restructured the global system of oil production in favor of oil-producing states and away from an oligopoly of dominant Anglo-American oil firms, the "Seven Sisters". In the 1970s, restrictions in oil production led to a dramatic rise in oil prices with long-lasting and far-reaching consequences for the global economy. Since the 1980s, OPEC has had a limited impact on world oil-supply and oil-price stability, as there is frequent cheating by members on their commitments to one another, and as member commitments reflect what they would do even in the absence of OPEC.

Selected biography

William Thomson, 1st Baron Kelvin, OM, GCVO, PC, PRS, FRSE, (26 June 1824 – 17 December 1907), widely known for developing the Kelvin scale of absolute temperature measurement, was a mathematical physicist, engineer, and outstanding leader in the physical sciences of the 19th century. He did important work in the mathematical analysis of electricity and thermodynamics, and did much to unify the emerging discipline of physics in its modern form.

Born in Ireland, Thomson studied at the University of Glasgow, Scotland. On graduating, he became a mathematics teacher at the Royal Belfast Academical Institution. During his life Thomson published more than 600 scientific papers and filed over 70 patents.

As early as 1845 Thomson pointed out that the experimental results of William Snow Harris were in accordance with the laws of Coulomb. Over the period 1855 to 1867, Thomson collaborated with Peter Guthrie Tait the Treatise on Natural Philosophy that unified the various branches of physical science under the common principle of energy. His inventions included the current balance for the precise specification of the ampere, the standard unit of electric current.

In 1893, Thomson headed an international commission to decide on the design of the Niagara Falls power station. Despite his previous belief in the superiority of direct current electric power transmission, he agreed to use alternating current after seeing a Westinghouse demonstration at the Chicago World's Fair.
